Lockdown may contribute to Thailand’s rise in dengue fever cases, study suggests

Social distancing and lockdown measures may have contributed to a rise in dengue fever in Thailand, according to a recent study funded by the Singapore Ministry of Health’s National Medical Research Council.

Researchers, which included scientists from the University of Singapore, examined dengue fever cases in Malaysia, Singapore and Thailand. No impact on the dengue transmission was found in Malaysia or Singapore, but in Thailand, they found that social distancing may lead to an increase in the number of coronavirus cases. They say the largest impact is in Bangkok Researchers say social distancing is expected to lead to 4.32 additional dengue fever cases per 100,000 people in Thailand each month.

Many people in Thailand stayed at home during lockdown measures put in place to control the spread to the coronavirus, but the study found that people in Thailand are typically bitten by dengue-carrying mosquitos at home rather than at work. Some people even travelled back home to their home provinces to be with their families during the lockdown period.

“Although it is possible for dengue infections to occur in workplaces, it was found in one study that 60% of dengue cases live less than 200m apart came from the same transmission chain, revealing that residential areas are a focal point of transmission.”
